Morning Y'all!

I am not new to slot machine repairs, but I am new to the IGT Reel Touch units. I picked one up last week, got the chips, and after a few hours and eliminating errors with cause and effect, I am now at the point where I have a working machine!

The problem is just one of a couple, and I was hoping maybe someone here would be able to help me to I can wrap up this unit.

First Off, the LCD is broken. When I first saw the unit it was completely white and the memory on the xp unit was beeping failed. When I went back days later with the truck and cash, I turned it on before moving it again, and this time the screen was completely black. I brought it home anyway and was able to hook an external monitor to it and touch the screen config to bypass the display comm error that I was experiencing. I take the unit apart and find that the LCD is in fact broken and bleeding out. WTB, if anyone has on available or can help guide me in the direction to find one??

Second, my bill validator works, and so does my ticket printer it says something on it like 'your location here' but when I put it back into the machine it acts like it wants to accept it and right before it would credit it to the machine, it spits it back out again... maybe I just need to key 31 it again and change a setting...

Thanks for any and all help!

Sorry one more thing to note, I will be getting my version info the next time I fire it up so I have it. My hard drive has some bad sectors as I already scanned it, but its working after a fix with check disk. I do have old laptop IDE hard drives laying around since I am a computer store, but we are about to relocate the store to a bigger location so a lot of the 'older' stuff is packed away. Does the drive have to be identical to boot, that is my only concern right now it has a 5400 rpm hitachi 40gb ide in it.

I also have a PS2 Keyboard handy if need be.

In the home owner world of slots
the tickets will not be accepted by
the bill acceptor without the casino
mainframe.
You can get the â€œBetter titoâ€ system that
can give you the ability to accept tickets.

Real Touch run on XP embedded operating system using a proprietary IGT boot chip. They are not user friendly.
That is why I asked on your previous post whether it was a bios 1 or 2 boot chip. If it is bios 1 you can not check or fix the hardrive with another windows computer. It adds files to the drive and it is rendered basically useless.
Bios 2 you can get away with looking at the files with a USB adaptor on another computer. They are not interchangeable as the files all must match.
The best way to make a hardrive is to clone it from a working one. There are 3 partitions on the hardrive, one holds the operating system (RFA), another partition holds the game file(BGM) and the igt sub system(ATA) I'm curious to know how you are getting the machine to operate without a working top box? Or is as you say the LCD screen itself is what is broken? PM me I think I may know some folks here that have top boxes for sale.

Strangely enough, the machine has been on for about 4-5 hours, with an external monitor hooked to it up, playing away... and oddly the screen turn on. it is all white, with no display, this could be because of vga connected or maybe a setting in bios?

As to answer your question to that, it boots up with bios 2006 on the screen, here are my other specs...

rfa: rfa
ata: ata20022
bgm: bgm20155

currently the screen is all white and it appears to have a light halo around the boarders.

Your inbox is full

Wow never had the LCD go bad it is usually the top box computer or hard drive that goes bad.
The touch screen does not operate through the VGA port that is why it still works on the native screen. It is a separate piece of glass in front of the native LCD and has it's own wiring. Most of the connections are really brittle and break if you look at them wrong. Try reseating the plug on the MPU inside the top box. It is the plug that has the very fine multi colored wires. That plug is the output to the LCD display. It does not appear to be getting the signal. The high voltage LCD light driver is good since you are getting a white screen.
Usually the LCD screen in these are bullet proof.
Still need to know if it is bios one or two. I'm assuming it's bios 2 because if it was bios one you would have dorked the hardrive when you looked at it. Bios two starts with a green and yellow energy star.
You will need this info if you get a replacement top box.
Haywire slots had some top boxes for sale not too long ago try him.
See if reseating the little plug I mentioned above first.
Let me know what happens.

I shut the machine down, checked the cables for the screen, they go to a usb port on the inside? I think thats for touch, I did not open the other square behind the motherboard yet.

Thanks

it has bios 2

The USB is for the touch screen.
Try reseating the very small long plug with the very tiny wires that goes to the mother board.

qbert · « **Reply #8 on:** August 05, 2018, 04:41:34 PM »

This is a picture I used to show another where the bios chip is, but the plug I want you to reseat is the one closest to the edge of the red circle on the right side.

I reseated that cable and oddly enough got the bad memory beep. So I pulled the memory, swapped it. system booted up, i calibrated the screen, it showed the door open call attendant screen very briefly, and then a red screen came up for about 5 seconds, the most I could read was basically not enough ram to support the game... I am starting to think there is not enough ram for the video driver and the game to boot... I ordered 2 brand new pc1333u 256mb chips, so I should be seeing them sometime at the end of the next week. Do you think insufficient ram could be the cause of the screen not coming on?

Thanks!

Rarely the RAM goes bad it is 99% of the time poor connections. If you were playing the game before it saw all of the RAM. Gently remove the sticks and lightly clean the contacts with a pencil eraser. Remove and reinsert them a few times and you should be good to go. When it is booting and checking the RAM if it only makes it to 25xxxxK shut off and reseat. It must get to 52xxxxK.
So the screen is now working?

Remember your working on a circa 1990s computer that operated continuously for more than 7-10 plus years and probably was never cleaned until the HD was replaced.(originals were only 20gb) The HD is usually the weakest link I've started using SSDs. Everything is old and brittle be careful. Contacts and bad connections are the usual suspects.

Still trying to PM you, please empty your mailbox.
Or better yet be a contributing member and then your mailbox is not limited.

I cleared my inbox, and let me clear it up for confusion.

This is a 2004 machine, it is still rocking the IDE 2.5 hard drive. I removed the lcd connection, reseated it, and the RAM started beeping at me that it was bad, just like it did when I bought the unit. I took the ram out blew out all the dust, and put them back in, but after the reseating of the cables, for the LCD the ram beep came back. So I took the sticks out, put them back in and it booted up... I got almost all the way booted to play and then it came on the screen about the video game insufficient memory error. So I ordered new memory to avoid this problem in the future. I have seen memory go bad, I own a repair shop but unfortunately I don't stock pc133u anymore. But my question is, do I have to program the screen to get it to boot with bios? I did remove the batteries and replace them prior to doing a ram clear. So I may be missing a step to get the screen to boot on.

Thanks

Please read my last three posts again.
Try cleaning the RAM contacts and reinstall.
If your 2.5 ide drive is 40gb big it was replaced before you got the machine, originals were only 20gb.
After battery replacement all you should do is use the keyboard press the delete key until the bios comes up. Set the time and date and save optimized defaults.
Then reboot without the keyboard and you should be good to go. Like I stated on the previous post if you were able to play the game with the other monitor your RAM was working.
The monitor in the machine does not use any more RAM.
Just be sure on boot the memory checks all the way to 52x,xxxK if it only counts to 25 reinstall the memory. One more thing you can try is reseating the daughter board where the monitor plug is, if the monitor is working now just leave it alone.
2004? The machine is still 14 years old. How many 14 year old working computers do you have in your shop? My point was it was designed in the late 90s and that is where it is from a technology stand.
Report back with your progress.

Hello,

Thanks for responding, upon further inspection it appears that where was dust in the dim slots, I cleaned them and the memory and it is working fine to boot, but at the same time still not lcd display, only external monitor. The board you are referring it the little orange one thats a funny shape plugging into the motherboard, does it pull straight out? I don't want to risk damaging it.

qbert · « **Reply #16 on:** August 06, 2018, 10:10:55 AM »

Did the LCD work at all since we started?
Also I'm assuming you have the VGA external unplugged when your trying this.
Can't remember if the board has a screw holding it down or not but I believe it pulls straight up. Just to be sure the board that has the plug with the very fine wires.
Is it still an all white screen?

Qbert can I ask you a question?Sorry to interrupt this topic..
Do you know what the generic replacement motherboard is for the top box in this machine?
Thanks

If I transfer all the stuff (processor,ram) from my bad board to this one it will work?
